Given the value of SSP and the values loaded into D6/D7 (which match the
ROM shadow at address 0), it is clear that SP was 0 at $48ea. So it
looks like A1 is just pointing at a block of zeros, not at a valid task
struct.
Maybe the allocation for the task struct failed? I will check that. Thanks for
your analysis!
